Iceland's parliament voted unanimously to legalize same-sex marriage in 2010. Only four years after this ruling, these pictures were taken and posted on Instagram by the police department in Iceland's capital, Reykjavik.

Iceland is also very good at presenting a brave face to researchers. The World Happiness Report has managed to come away with the frankly laughable impression that Iceland is the second-happiest country in the world.

The Netherlands made same-sex marriage legal in 2001.

In addition to having to endure same-sex marriage, the people of the Netherlands have consistently had to endure being listed among the 10 happiest countries in the world by the World Happiness Report.

Spain legalized same-sex marriage on July 3, 2005.

This set in motion a devastating series of events that led to a result that Spaniards are still shaking their heads about. In 2009, a poll of 15,000 people conducted by a global research firm determined that Spain has the best lovers in the world.

A mere eight years after the ruling, the Spanish wine industry, which had clearly gone completely insane after the change, topped the world rankings. Spanish vineyards produced enough wine to fill 6.7 billion bottles.

Six years later, the stalwart resilience of Canadians in the face of a national crisis was poignantly demonstrated: A 2011 study found that 9 out of 10 Canadians age 12 or older were “satisfied or very satisfied” with their lives.

Norway legalized same-sex marriage on Jan. 1, 2009. All they've managed to do since is come in No. 1 in the Human Development Index (HDI), the UN's measure of quality of life for all the world's nations, every year.

Their lives shattered by the ruling, French people turned to one another for comfort. How else to explain the 2014 finding that 87% of French people knew someone they could rely on in times of need?

Ironically, tourists flocking to France to commiserate over their national disaster have made it the most popular tourist destination in the world, but the French psyche has clearly never recovered — the country now makes over 1,000 kinds of cheese, an obvious sign of severe mental anguish.

Uruguay became the 14th country to legalize same-sex marriage, on Aug. 5, 2013.

This is probably why they could only manage a pathetic third place in the Corruption Perception Index last year. Apparently having the third-least corrupt government is "good enough" for Finland.

To emphasize Finland's disastrous slide into depravity, they managed to come in at only fifth place in best overall education in the world last year, and are barely hanging onto their No. 1 spot in the world rankings of press freedom.

In May 2015, Ireland became the first country to legalize same-sex marriage by popular referendum.
